Sorry i got a question. Is it that in patch 1.0.7.0 i can only have one kind of a weapon at a time? When i replace the line in the weaponsinfo.xml i end up with only the rockets on my LMB and the RMB does nothing :( And if i try to use the littlebirdrockets.asi it will crash my game :(

@Chabat: Yes, mate. We did need JulioNIB Scrips and he is back from Christmas and year-end holidays now. The script is almost ready, it is comprehensive, sophisticated and wonderful. It is developing for use by all models of fighter jets, will have capacity to launch missiles lockable, drop bombs, shoot guns, ejection of the pilot, flame in the engine outputs and much more. JulioNIB will release a first version very soon with most of these functions to be used for jets and jets fighter`s modelers in their releases xD
